OBJECTIVE: To compare clinical effect of anterior tibial plateau fracture line and anterior tibial fenestration reduction in treating anterolateral tibial plateau column fracture combined with posterior lateral column collapse. METHODS: Fifty-two patients with Schatzker typeⅡ tibial plateau anterolateral column fracture combined with posterolateral column collapse admitted from January 2016 to December 2021 were retrospectively analyzed and divided into two groups according to fracture reduction methods. There were 27 patients in fracture line group, including 19 males and 8 females, aged from 26 to 62 years old with an average of (43.2±11.4) years old;the time from injury to operation ranged from 4 to 8 days with an average of (5.8±1.5) days;treated with reduction and internal fixation via fracture line of lateral platform front. There were 25 patients in fenestrate group, including 13 males and 12 females, aged from 22 to 69 years old with an average of (40.8±11.1) years old;the time from injury to operation ranged from 4 to 8 days with an average of (6.0±1.4) days;treated with tibial fenestration reduction and internal fixation. The amount of bone graft, operation time, fracture healing time and complications were compared between two groups. Posterior slope angle (PSA) and posterior slope angle of the lateral tibial plateau was compared before surgery, 2 days and 6 months after surgery. The knee function was evaluated by Hospital for Speical Surgery (HSS) at 2 days and 6 months after surgery, respectively. Fracture reduction was evaluated by Rasmussen anatomic score of knee joint. RESULTS: Both of group were followed up from 12 to 24 months (16.0±3.4) months. No redisplacement of fracture, internal and external inversion deformity of knee joint, or instability of knee joint were found between two groups during follow-up. In fracture line group, 1 patient occurred wound fat liquefaction and 2 patients occurred lower limb intermuscular venous thrombosis occurred. In fenestration group, 1 patient occurred joint stiffness, 1 patient occurred lower limb intermuscular venous thrombosis, and 1 patient occurred superficial wound infection;there were no significant difference in complications between two groups (P>0.05). Bone graft volume, operative time and fracture healing time in fracture line group were (3.6±2.3) cm³, (123.4±18.2) min and (13.8±1.8) weeks, while in feneplast group were (4.8±1.8) cm³, (135.5±22.5) min and (15.2±2.0) weeks, respectively;the difference between two groups was statistically significant (P<0.05). The collapse depth of lateral platform articular surface at 2 days and 6 months after surgery were (0.8±0.1) and (0.9±0.1) mm in fracture line group, which were lower than those in fenestration group (0.9±0.1) and (1.1±0.1) mm, respectively (P<0.05). After 2 days and 6 months, , PSA in fracture line group were (9.4±1.5) ° and (10.1±1.9) °, respectively, which were lower than those in fenestration group (10.5±1.5) ° and (11.3±1.9) ° (P<0.05). Rasmussen anatomical scores in fracture line group at 2 days and 6 months were 16(16, 18) and 16(14, 16) points, respectively, which were better than those in fenestrated group (16, 16) and 14(14, 16) points (P< 0.05). The collapse depth, PSA and Rasmussen anatomical score between two groups were better than those before surgery (P<0.05). There was no significant difference in HSS score between two groups at 2 days after surgery (P>0.05). At six months after surgery, HSS score in fracture line group (86.7±3.6) was higher than that in fenestration group (84.1±3.91) (P<0.05). HSS score at 6 months after surgery was better than that at 2 days after surgery (P<0.05). CONCLUSION Both anterior tibial plateau fracture line and anterior tibial fenestration could be used to treat anterolateral tibial plateau column fracture with posterior lateral column collapse. Compared with fenestration group, transfracture line group had advantages of less intraoperative bone grafting, shorter operative time, shorter fracture healing time, better articular surface reduction effect and better knee functional recovery.

The breakage pattern of unit particles during the production of oral solid dosage forms (OSD) is closely related to the quality of intermediate or final products. To accurately characterize the particles and study the evolution law of particle breakage, the Bonding model of the discrete element method (DEM) was used to investigate the breakage patterns of model parameters, particle shape and process conditions (loading mode and loading rate) on the dynamic breakage, force-time curve, breakage rate, maximum breakage size ratio and fracture strength of particles. The results showed that the particle breakage force was positively correlated with normal strength and bonded disk scale, negatively correlated with normal stiffness per unit area and tangential stiffness per unit area, and weakly correlated with tangential strength. The particle breakage rate was negatively correlated with the aspect ratio of the particles, and the maximum breakage size ratio was positively correlated with the aspect ratio of the particles; among the three loading modes, the breakage rate of compression breakage model was the largest, the breakage rate of shear breakage model was the second largest, and the breakage rate of wear breakage model was the smallest; the maximum breakage size ratio was positively correlated with the loading rate, the loading mode and the loading rate had no mutual influence on particle breakage rate, but had mutual influence on the maximum breakage size ratio. The research results will provide a theoretical basis for the shift of OSD from batch manufacturing to advanced manufacturing.
